ELK leak barrier before GAF-Elk roof deck protection is installed; DO NOT nailthrough the flashing. Secure the flashing by nailing at 18 inches (457 mm) on center

just beyond edge of flashing so that nail heads hold down the edge.

D Hips and Ridges:

1. Install GAF-Elk leak barrier along entire lengths. If ridge vents are to be installed,position the GAF-Elk leak barrier so that the ridge slots will not be covered.

E Roof Deck:

1. Install one layer of GAF-Elk roof deck protection over the entire area not protectedby GAF-Elk leak barrier at the eaves or valley. Install sheets horizontally so water

sheds and nail in place.

2. On roofs sloped at more than 4 in 12, lap horizontal edges at least 2 inches (51mm)and at least 2 inches (51mm) over eaves protection membrane.

3. On roofs sloped between 2 in 12 and 4 in 12, lap horizontal edges at least 19 inches(482 mm) and at least 19 inches (482mm) over eaves protection membrane.

4. 0Lap ends at least 4 inches (102 mm). Stagger end laps of each layer at least 36inches (914 mm).

5. Lap GAF-Elk roof deck protection over GAF-Elk leak barrier in valley at least 6inches (152mm).

F Deck-Armor Application

1. Deck-Armor shall be installed over a clean, dry deck.2. Install Weather Watch or StormGuard Leak Barrier at eaves, valleys, rakes,

skylights, dormers and other vulnerable leak areas.

3. Lay Deck-Armor over deck and overlap 3 (76mm) at side laps and 6 (152mm) atend laps.

4. For exposure to rain or snow, overlap 12 (305mm) at end laps.

5. For side and end laps: fasten Deck-Armor 12 (305mm) o.c. (6 (152mm)o.c. for highwind areas).

6. For middle of the roll: fasten Deck-Armor 24 (610mm) o.c. (12 (305mm) o.c. forhigh wind areas).

7. For exposure to rail or snow, completely cover all side laps, end laps and fastenerswith tape.

8. For long term exposure see complete Deck-Armor installation instructions for sidelap detail.

9. If roof may be exposed to high winds, apply tape over all fasteners at the center ofthe roll to prevent rain or snow from entering at the fasteners.

10. For slopes less that 2:12, a double application of Deck-Armor is required. Seecomplete Deck-Armor installation instructions for more information.

2. Vertical walls: Install eaves protection membrane extending at least 6 inches(152mm) up the wall and 12 inches (305mm) on to the roof surface. Lap the

membrane over the roof deck underlayment.3. Skylights and roof hatches: Install eaves protection membrane from under the built-

in counterflashing and 12 inches (305mm) on to the roof surface lapping over roofdeck underlayment.

4. Chimneys: Install eaves protection membrane around entire chimney extending atleast 6 inches (152mm) up the wall and 12 inches (305mm) on to the roof surface.Lap the membrane over the roof deck underlayment.

5. Rake Edges: Install metal edge flashing over eaves protection membrane and roofdeck underlayment; set tight to rake boards; lap joints at least 2 inches (51mm) andseal with plastic cement; secure with nails.

3.6 INSTALLATION OF SHINGLES

A General:

1. Install in accordance with GAF-Elk's instructions and local building codes. Whenlocal codes and application instructions are in conflict, the more stringentrequirements shall take precedence.

2. Minimize breakage of shingles by avoiding dropping bundles on edge, by separatingshingles carefully (not by "breaking" over ridge or bundles), and by taking extraprecautions in temperatures below 40 degrees F (4 degrees C).

3. Handle carefully in hot weather to avoid scuffing the surfacing, or damaging theshingle edges.

B Placement and Nailing:

1. For maximum wind resistance along rakes & eaves, install any GAF-Elk starter strip

containing sealant or cement shingles to underlayment and each other in a 4"(102mm) width of asphalt plastic roof cement.

2. Secure with 4, 5, or 6 nails per shingle per GAF-Elks instructions or local codes.

3. Placement of nails varies based on the type of shingle specified. Consult theapplication instructions for the specified shingle for details.

4. Nails must be driven flush with the shingle surface. Do not overdrive or under drivethe nails.

5. Shingle offset varies based on the type of shingle specified. Consult the applicationinstructions for the specified shingle for details.

C Placement and Nailing:

1. Beginning with the starter strip, trim shingles so that they nest within the shinglelocated beneath it. This procedure will yield a first course that is typically 3 (76mm)to 4 (102mm) rather than a fully exposed shingle.

2. For maximum wind resistance along rakes, install any GAF-Elk starter stripcontaining sealant or cement shingles to underlayment and each other in a 4"(102mm) width of asphalt plastic roof cement.

3. Laterally, offset the new shingles from the existing keyways, to avoid waves ordepressions caused by excessive dips in the roofing materials.

4. Using the bottom of the tab on existing shingles, align subsequent courses.

5. *Note: DO NOT install standard sized shingles (5 exposure) over metric (5 5/8exposure) shingles, as it will overexpose the shingles and reveal the nails. Usestandard alignment methods to assure proper shingle placement.

6. Secure with 4, 5, or 6 nails per shingle per GAF-Elks instructions or local codes.

7. Placement of nails varies based on the type of shingle specified. Consult theapplication instructions for the specified shingle for details.

8. Nails must be driven flush with the shingle surface. Do not overdrive or under drivethe nails.

9. Shingle offset varies based on the type of shingle specified. Consult the applicationinstructions for the specified shingle for details.

a Snap diverging chalk lines on the metal flashing, starting at 3 inches (76mm)each side of top of valley, spreading at 1/8 inch per foot (9mm per meter) to theeaves.

b Run shingles to chalk line.

c Trim last shingle in each course to match the chalk line;0 do not trim shingles toless than 12 inches (305mm) wide.

d Apply a 2 inch (51mm) wide strip of plastic cement under ends of shingles,sealing them to the metal flashing.

2. Install valleys using the "closed cut valley" method:

a Run the first course of shingles from the higher roof slope across the valley atleast 12 inches (305mm).

b Run succeeding courses of shingles from the lower roof slope across the valleyat least 12 inches (305mm) and nail not closer than 6 inches (152mm) to center

of valley.
